Hello Caroline.

Thank you for your purchase.

Unfortunately, there is no documentation about this, since it is a custom solution, but I can tell you here how you can do that:

To hide the "Apply and add new", "Prev" and "Next" buttons, you need to add the following CSS to your Custom CSS field in main settings of wpDataTables:

.wdt-apply-edit-button {
display: none !important;
}
.wdt-prev-edit-button {
display: none !important;
}
.wdt-next-edit-button {
display: none !important;
}

This will just hide the button from front-end, but anyone who knows a thing or two about CSS can inspect the page and enable it again.

I don't know if you'll find it useful to hide it for all your tables, but if you do, here's how to remove it from the modal completely:

Open ../wp-content/plugins/wpdatatables/templates/frontend/edit_dialog.inc.php and around line 158 find these lines of code:

<button id="<?php echo $this->getId() ?>_prev_edit_dialog" class="btn bgm-gray btn-icon-text waves-effect wdt-prev-edit-button">
        <i class="zmdi <?php if(in_array($currentSkin, $skinsWithNewEditButtons )) { echo 'zmdi-chevron-left'; } else { echo 'zmdi-skip-previous'; }?>"></i>
        <?php _e('Prev', 'wpdatatables'); ?>
    </button>
    <button id="<?php echo $this->getId() ?>_next_edit_dialog" class="btn bgm-gray btn-icon-text waves-effect wdt-next-edit-button">
        <?php _e('Next', 'wpdatatables'); ?-->
        <i class="zmdi <?php if(in_array($currentSkin, $skinsWithNewEditButtons)) { echo 'zmdi-chevron-right'; } else { echo 'zmdi-skip-next'; }?>"></i>
    </button>
    <button id="<?php echo $this->getId() ?>_apply_edit_dialog" class="btn btn-success btn-icon-text waves-effect wdt-apply-edit-button">
        <i class="zmdi <?php if(in_array($currentSkin, $skinsWithNewEditButtons)) { echo 'zmdi-check-circle'; } else { echo 'zmdi-check';  }?>"></i>
        <!--?php _e('Apply and add new', 'wpdatatables'); ?-->
    </button>

Just comment them, so they look like this:

//    <button id="<?php echo $this->getId() ?>_prev_edit_dialog" class="btn bgm-gray btn-icon-text waves-effect wdt-prev-edit-button">
//        <i class="zmdi <?php if(in_array($currentSkin, $skinsWithNewEditButtons )) { echo 'zmdi-chevron-left'; } else { echo 'zmdi-skip-previous'; }?>"></i>
//        <?php _e('Prev', 'wpdatatables'); ?>
//    </button>
//    <button id="<?php echo $this->getId() ?>_next_edit_dialog" class="btn bgm-gray btn-icon-text waves-effect wdt-next-edit-button">
//        <?php _e('Next', 'wpdatatables'); ?-->
//        <i class="zmdi <?php if(in_array($currentSkin, $skinsWithNewEditButtons)) { echo 'zmdi-chevron-right'; } else { echo 'zmdi-skip-next'; }?>"></i>
//    </button>
//    <button id="<?php echo $this->getId() ?>_apply_edit_dialog" class="btn btn-success btn-icon-text waves-effect wdt-apply-edit-button">
//        <i class="zmdi <?php if(in_array($currentSkin, $skinsWithNewEditButtons)) { echo 'zmdi-check-circle'; } else { echo 'zmdi-check';  }?>"></i>
//        <!--?php _e('Apply and add new', 'wpdatatables'); ?-->
//    </button>

and that will remove them from the "New Entry" modal.

To change the size of the labels inside the dialog, please use this CSS:

.wpdt-c .wdt-edit-dialog-fields-block {
font-size: 20px !important;
}

And to change the font size for the input fields, you can use this:

.wpdt-c .input-sm {
font-size: 20px !important;
}

I hope this helps.

You're welcome, Caroline
