I try to get some help from you to spot what I am doing wrong (what I am missing) on applying search tools and filters in the admin of Joomla 3.8 in my own component.
I am pulling my hairs out since I cannot figure out why the search and the filters are not working for me, in other words, the search field is not responding, the search tools/hidden filter does not open.
Only if I click on the clear filters/search button then it refreshes the page with cleared filters. Sorting of fields/columns are working. My only guess is that it is a Jquery/Javascript problem but I do not really know what. Please help me if you can. Thanks in advance!
We are in the view/model called 'products', so my filters' xml:
../models/forms/filter_products.xml
<?xml version="1.0" encoding="utf-8"?>
<form>
<fields name="filter">
<field
name="search"
type="text"
label="COM_MOREPRODUCTINFO_SEARCH_IN_TITLE"
hint="JSEARCH_FILTER"
class="JSEARCH_FILTER"
/>
<field
name="availability"
type="list"
label="JOPTION_SELECT_AVAILABLE"
description="JOPTION_SELECT_AVAILABLE_DESC"
default=""
onchange="this.form.submit();"
>
<option value="">JOPTION_SELECT_VALUE</option>
<option value="1">Available</option>
<option value="0">Unavailable</option>
</field>
</fields>
<fields name="list">
