I am building a module, or component not sure yet, but I need to have a some options that depend on another option. For example, if you choose "A" then options 1, 2 and 3 appear. If you choose "B" then 4,5 and 6 appear.
I can make everything appear at once just sending in the but can I make some params only appear after another is chosen?
Thank you.
This should be reasonably simple to achieve using javascript (i.e. it will run on the user's PC without a round-trip back to the server).
Put all the controls on the form, but for the ones that you do not wish to display initially use the CSS attribute {display:none} and they won't show.
Then use the onclick() event of the control which will determine whether other controls are made visible to show / hide controls as you wish.
There is an example of something similar to this (not within Joomla, but there is no reason (that I can think of) why this won't also work fine within a Joomla module / component) here: http://www.java2s.com/Code/JavaScript/Development/Makebuttoncontrolvisibleorinvisible.htm

Like the topic say I want to overwrite/change the "Menu Manager: Edit Menu item" layout. To illustrate my question:
In the picture whiche is shown I want to change the labels: Layout, Option, Integration.... and add some other options to it. How can I do it? Or is this even possible?
In order to change the text, simply use language overrides, google is your friend.
In order to add functionality, let's first of all explain what we're talking about to ensure we're on the same page.
Joomla components have views which can have one or more layouts, i.e.
/components/com_content/views/category/tmpl/ contains two layouts, blog and default.
A layout can additionally contain an .xml manifest (in our case, blog.xml and default.xml) allowing us to create a menu item for the specific view/layout combination. The .xml file contains the parameters that the user will set, you can add your own as well.
When you want to change Joomla, usually there is a way to do so without touching the core, which would be pretty bad, as any Joomla! updates would break your work.
For the view layouts a special feature called template override was developed, which allows you to create an alternative to the view layout in a safe place (under your template folder, in this case your admin template), and this is the most elegant and effective way to achieve your result.
Beware though, you are just creating a layout, most likely you will want to add functionality, if it's complex you might be better off creating a dedicated component to keep the code clean. Or you can just put all the logic in your view, query the database from there. But in this latter case, get paid, and run away. Never answer the phone to the customer again.
A final alternative is to write a system plugin that will manipulate the page markup after it was generated in the event onAfterRender(). This is a simple and good approach if you only want to add a button or make minor changes, but if you do anything more than that, see the above advise about running away.
I've created an alternative layout for one of my articles which can be applied successfully, but as has been highlighted in various forums: if you view the article using the Single Article menu type the alternative layout doesn't get applied because of an XML override.
I have a Joomla site that is setup for Sales and Support where the article info such as date, hits etc is useful but on the marketing side none of that is needed, hence an alternative layout would work well.
I want to know how to enable my alternative layout using the Single Article menu type - I've already got the layout how I want it (testing it by having it overwrite default.php) but want to set it up as marketing.php instead and only have it applied to what is needed.
You're probably not going to like this answer because you have already written you're alternate view. If you were rewriting it to begin with, why would you not write in a way that the side bar parameters (date, hits, ect) are within a container that is only loaded conditionally. This way you would only have one view to worry about and a lot less headaches.
I have to convert a static site for a client and it has to retain the exisiting layout.
Fortunately, most of the pages don't have to be editable, so for those I was going to use more or less the existing html.
The challenge I am having is that for many of the pages that do need to be editable, the content is laid out in columns (2, 3 and sometimes mixed)
This ( http://globalstrategies.org/index.php/give/hope-partners ) is an example of a page like that, and you can see others on the site where the layout is relatively complex.
I had thought of creating a jce stylesheet that would at least layout the page in the editor in a reasonable way (a bit like a responsive site, by having the columns stacked one after the other) , but I am concerned that my client may accidentally delete the surrounding classes/divs that create the more detailed structure.
I'm pretty familiar with Joomla and have built quite a few sites, but I've not used an cck tools and was hoping not to have to do that in this case, though maybe now is the time to learn.
Any advice / recommendations would be welcome !

Maybe ContentBuilder could do in your case, it's fairly easy and creates super-simple code, I've accomplished similar tasks with it. You provide the user with 3 fields (one per column) and create a layout for its display.
Another alternative is possibly even easier: you could override the use of the page functions in a template override of com_content/article, instruct the user to insert at most 2 page breaks, and use the page breaks to build the layout as you require.
If your sites is upgraded to the Joomla 3 you can use the build-in Bootsrap to do the layout.
You can find some more information how you can achieve this in the following page:

I'll start out by mentioning that there is a developer forum for Zoo and I have used it already. My purpose posting here is that I typically get a thorough answer within minutes or hours at SO, whereas the responses on dev forums can be slow or non-existent due to the smaller population base.
My question regards Yootheme's ZOO 2.3.2. By default, a product "Frontpage" appears to have a "Categories" box rendered on top of the items. If one turns off all the available options in Frontpage/Template configuration (hide Titles, Count, Descriptions, etc.), an empty box still remains on top of the items.
I've been able to manually remove the box in its entirety by addressing the following file:
media/zoo/applications/product/templates/default/frontpage.php, and commenting out lines 84-92:
<!-- <?php
// render categories
if ($this->category->childrenHaveItems()) {
$categoriestitle = $this->application->getParams()->get('content.categories_title');
echo $this->partial('categories', compact('categoriestitle'));
}
?> -->
Seems like there should be a more eloquent way of doing this on the admin backend, but I couldn't find one. Am I missing something or is my solution the best one?
ZOO is designed to easily be able to modify the built in templates to suit your needs. ZOO templates are meant to be overridden much like Joomla uses template overrides. Rather than editing the default template, you simply create a new template that does what you want it to. The default template should not be changed.
Here is the documentation on ZOO templates - http://www.yootheme.com/docs/home/item/create-a-new-template
Rather than edit the file you mention above, you make a new template here -
media/zoo/applications/product/templates/YOUR-TEMPLATE-NAME/frontpage.php
Then do all the changing you want without messing up the default.
There is an easier way: First, you must identify what calls the item called "frontpage". In PURE yootheme at least it is called from "home" in the "mainmenu". So click "home" buton of the mainmenu, then over the right menu "Parameters(Basic)" you just chose "-select aplication-" instead "frontpage" and that's it.The Frontpage and its "box" are now gone. At least it works for me.
I want to know that can i change the navigation menu dynamically,i am having two tabs on the basis of which i want to render the navigation menu.How can it be done
Thanks in advance
For usability reasons, the global navigation generally shouldn't change. Users will expect to see the same options available to them and will get confused (and leave) if they aren't.
Could you explain the requirement more?
EDIT:
Usability issues aside, try adding all necessary items to the top nav, then use Javascript to toggle between tabs. If you don't want to change the navigation PHTML files to add IDs to them, you can use the existing classes to target which nav items to show and which to hide.
Since Magento stores cannot function without JS anyway, you should be pretty safe with that solution. Preferably, you can change the top nav's template (I believe app/design/frontend/base/default/template/page/template/links.phtml in 1.4) to use IDs for those LIs as well, in which case you can target those instead.
Thanks,
Joe
