Question:
I want to hide the side filter column of the store page if a given product category is selected. For instance, if in the URL query param there is an entry for a given category, I want to hide the filter, otherwise the filter remains.
I tried to select only the filter via the Velo API but I could not find a way, it only allowed me to select the entire component (including filter and product cards). And I was not able to use DOM manipulation directly - apparently itβs not possible to do that in the dev tools.
Any suggestion on how to do it?
I found a way of doing it with a custom script.
But let me know if there is a proper way of doing it via Velo.
Thanks
As long as you do not use to much predefined stuff and generate all elements, functions & features by your own β wix works.
As soon as you start to use PREDEFINED-WIX-STUFF only β you get problems.
Like you already mentioned β you start to search for WORKAROUNDS to work around restrictions, because predefined stuff like Wix-APPs are not really capable to cover all of users wished features & functions β this is where CUSTOM-CODE comes into place.
The bad thing β if there are no APIs you can use β the problems start to get bigger and bigger and it starts to get harder to find a WORKAROUND.
This is normal on the Wix Platform.
But the good thing is β there is always a way for self created stuff using CUSTOM-ELEMENTS or HTML-COMPONENTS.
But WIX is surely working on new expanded APIs to improve customization capabilities & possibilities. 
I hope so.
