I have found the theme template for exposed filter form of view.
Template name: views-exposed-form.tpl.php
Inside the template I found the $widgets array
and for loop
for each $widget
display in form.
But it is rendered HTML widget How can I get only values array for each combo box to render output for my combo box as I want?
for instance:
I have one combo called Country: Country has hierarchy level of list
Asia
- India
- Sri lanka
- thailand
- Indonesia
etc...
So, I would like to make my combo just like this
http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_optgroup
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
This will identify the parent / child category in combo? can we do this directly in drupal 7 Views for Expoesd Filters Combo ? or How can I theme myself to override its HTML?
