Dropdown list with conditions on other dropdown list - validation

Question

How can I make a drop-down list from several lists with a condition from another drop-down list?
Using my image above, let's say I on the first drop-down list (this one is a simple one) select "Furniture"... I would like the second drop-down list to only show the furniture. Same thing with the third drop-down list, would like only the color of my second choice to be shown there.
Did try to place on the criteria "Custom formula" in the "Data validation" one of this two formulas but does not work...
=FILTER(Object,Type = E2)
or
=QUERY(A:C,"SELECT B WHERE A='"&E2&"' ", 0)
Did read in some other topic here that it was not possible with formulas and I could not find an app script for it. How can i place conditional rules and make only appear the values i want on the drop-down menu instead all of them ? I think it has something to do with the "withCriteria(criteria, args)" however i am not understanding how to apply it.
About the list ... it will be compose maybe with 2k lines (each line 3 columns). First column will only have (maybe) 6 or 7 different values. Second about 70 or 80 and third all different. The order will be random cause new values could be added and i can be adding a new Furniture or Animal ...
This is the code i have now
function onEdit(e) {
var range = e.range;
var ss = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1');
if ( range.getRow() > 1) {
if ( range.getColumn() == 5) {
var cell_Range = ss.getRange( range.getRow(), range.getColumn() + 1);
var cell = cell_Range.getCell( 1, 1);
var rangeV = SpreadsheetApp.getActive().getRange('B2:B13');
var rule = SpreadsheetApp.newDataValidation().requireValueInRange(rangeV).build();
cell.setDataValidation(rule);
}
else if ( range.getColumn() == 6 ) {
var cell_Range = ss.getRange( range.getRow(), range.getColumn() + 1);
var cell = cell_Range.getCell( 1, 1);
var rangeV = SpreadsheetApp.getActive().getRange('C2:C13');
var rule = SpreadsheetApp.newDataValidation().requireValueInRange(rangeV).build();
cell.setDataValidation(rule);
}
}
}

Solution:
Use Datavalidation requireValueInList
Flow:
Get All options A1:C as a array
Filter A(Col1) if edited value in E(Col5) is present in it
Retrieve corresponding Col2(B) as options and build data validation based on it
Offset the edited range by 1 column and set DataValidation
Sample Script:
function onEdit(e) {
const SETTINGS = {
//Edited Column : Column to Check(First col in optionsDataRange is considered 1)
5: 1,
6: 2,
};
var editedRange = e.range,
editedSheet = editedRange.getSheet(),
val = e.value,
col = editedRange.columnStart,
row = editedRange.rowStart;
/*Exit clause(s)*/
if (
Object.keys(SETTINGS).indexOf(col.toString()) === -1 || //If edited col is not in settings
editedSheet.getName() !== 'Sheet1' ||
row > 5
)
return;
var optionsDataRange = editedSheet
.getRange(1, 1, editedSheet.getLastRow(), 3)
.getValues();
/*Only get options where val is present in optionsDataRange*/
var options = optionsDataRange
.map(function(e) {
return e[SETTINGS[col] - 1] == val ? e[SETTINGS[col]] : null;
})
.filter(function(e, i, a) {
return e !== null && a.indexOf(e) === i;
});
var dv = SpreadsheetApp.newDataValidation()
.requireValueInList(options)
.build();
editedRange.offset(0, 1).setDataValidation(dv);
}
