How to customize the JoomD search module?
Ques: I’d like to edit the source code of the search module to make two drop menus for the categories, one for top categories and the other for the sub categories of the selected parent category,
i’ll do it on my own i just love to have directions or hints from you.
Ans: It’s mod_joomd_search module you want to modify.
Template file is mod_joomd_serch/tmpl/default.php
Database file is mod_joomd_search/helper.php.
Category table __joomd_category and the parent column is used to save the parent id.
If you want to send Ajax reQuest you can use JoomD component controller to execute that reQuest.
