Can I add a text field , drop down and check box along with columns that i search from SQL ? If yes , can you tell me how.

Hello,

The extension doesn't support described feature.

Isn't there any file I can tweak to add those feature? Need to implement those feature urgently. Or if there is an add-on you can provide.

If you don't use "Server side pagination" option, it is possible to create a custom HTML search form outside the module (for example place the search from to an article and load the module to the same article) and use request variables in "WHERE" clause of "SELECT" SQL query. Request variables are used in the following way:

{$REQUEST:VAR_NAME}

Where VAR_NAME is a name of request variable. For example:

SELECT
*
FROM
tbl
WHERE
price > {$REQUEST:price}
