Answer 1

Change your code in category class like this :
class category extends Model
{
public $table = "category";
public function products()
{
return $this->hasMany('App\products','p_id');
}
}
Then you can get all you product related to that category like this :
#foreach(App\category::all() as $firstmenu)
#foreach($firstmenu->products())
// All of product in this one category
#endforeach
#endforeach

Answer 2

You need to update your category model
category.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class category extends Model
{
public $table = "category";
public function products()
{
return $this->hasMany('App\product', 'ID', 'p_id');
}
}
category view
<div class="nav-panel__nav-links nav-links">
<ul class="nav-links__list">
#foreach(App\category::with('products')->where('p_id',0)->first()->products as $firstmenu)
<li class="nav-links__item nav-links__item--has-submenu ">
<a id="cate" class="nav-links__item-link" href="{{$firstmenu->cate_name}}">
<input type="hidden" name="cate" value="{{$firstmenu->id}}">
<div class="nav-links__item-body">
{{$firstmenu->cate_name}}
<svg class="nav-links__item-arrow" width="9px" height="6px">
<use xlink:href="public/assets/images/sprite.svg#arrow-rounded-down-9x6"></use>
</svg>
</div>
</a>
<li>
</ul>
</div>
