Hello Larry.

I am sorry, but unfortunately something like this is not possible with the plugin's built-in features. You see, the filter labels are being dynamically added, so there is no custom CSS you can add to remove the colon:

Thank you for your suggestion, though. I'll forward it to our development team, and they'll add it to our idea list and look into some possible solutions on plugin side in the future.

Best regards.

Hi Larry,

Aleksandar is out of the office today and I will help you.

If I understand you right you need to remove character : from Responsive mode? (attachment)

If that is true you need to remove it in file wp-content/plugins/wpdatatables/assets/js/responsive/datatables.responsive.js around line 126 you will find this

this.rowLiTemplate = '<li><span class="columnTitle"><!--column title--></span>: <span class="columnValue"><!--column value--></span></li>';

and you have to replace with this or insert character that you need instead of :

this.rowLiTemplate = '<li><span class="columnTitle"><!--column title--></span><span class="columnValue"><!--column value--></span></li>';

Also, you need to turn off option Use minified wpDataTables Javascript on tab CUSTOM JS and CSS in settings of plugin. If you are using some cache plugin please clear the server and browser cache.

About the character in Filter labels when you are using option Filter in form (filters above the table) you can find it in file wp-content/plugins/wpdatatables/templates/frontend/filter_form.inc.php around line 23 you will find this 

<label><?php echo $dataColumn->getFilterLabel() ? $dataColumn->getFilterLabel() : $dataColumn->getTitle() ?>:</label>

and you have to replace it with this or insert character that you need instead of :

<label><?php echo $dataColumn->getFilterLabel() ? $dataColumn->getFilterLabel() : $dataColumn->getTitle() ?></label>

Please note that this will be over written in next update so you need to do it again.

Best regards.

Hello again Larry.

Our plugin packs all those in a single minified file, that's why you need to disable it.

Best regards.
