Hello Gary

Unfortunately, there is no built-in option at the moment, but we will add it in one of the next updates.

You can change it in code in file wp-content/plugins/wdt-master-detail/class.masterdetail.wpdatacolumn.php around line 51 you will find this

$formattedValue = "<form class='wdt_md_form' method='post' target='_blank' action='{$renderAction}'>
                                       <input class='wdt_md_hidden_data' type='hidden' name='wdt_details_data' value=''>
                                       <input class='master_detail_column_btn {$buttonClass}' type='submit' value='{$buttonLabel}'>
                                       </form>";

and you have to change target="blank" to target="_self"

$formattedValue = "<form class='wdt_md_form' method='post' target='_self' action='{$renderAction}'>
                                       <input class='wdt_md_hidden_data' type='hidden' name='wdt_details_data' value=''>
                                       <input class='master_detail_column_btn {$buttonClass}' type='submit' value='{$buttonLabel}'>
                                       </form>";

also in the same file on line 64, you will find this

$formattedValue = "<form class='wdt_md_form' method='post' target='_blank' action='{$renderAction}'>
                                       <input class='wdt_md_hidden_data' type='hidden' name='wdt_details_data' value=''>
                                       <input class='master_detail_column_btn md-link' type='submit' value='{$content}'>
                                       </form>";

and you have to replace it with this:

$formattedValue = "<form class='wdt_md_form' method='post' target='_self' action='{$renderAction}'>
                                       <input class='wdt_md_hidden_data' type='hidden' name='wdt_details_data' value=''>
                                       <input class='master_detail_column_btn md-link' type='submit' value='{$content}'>
                                       </form>";

Then, go to wp-content/plugins/wdt-master-detail/templates/md_modal.inc.php and change line 52 just like you did the others, so change this:

<form  class='wdt_md_form' method='post' target='_blank' action='<?php echo $renderAction; ?>'>
                <input class='wdt_md_hidden_data' type='hidden' name='wdt_details_data' value=''>
                <input class='master_detail_column_btn' type='submit' value='Submit'>
            </form>

To this:

<form  class='wdt_md_form' method='post' target='_self' action='<?php echo $renderAction; ?>'>
                <input class='wdt_md_hidden_data' type='hidden' name='wdt_details_data' value=''>
                <input class='master_detail_column_btn' type='submit' value='Submit'>
            </form>

That one's for row click.

Basically, look only for "target='_blank'" and change it to "target="_self'" and that's it.

I hope that helps.

You're welcome, Gary.

Keep in mind that you'll need to do this again when the plugin updates, until we include it in the plugin.
