Hello Jean

Thank you for your purchase.

I can only help you open the Master-Detail page in the same tab, not in a new tab. To do that, please go to /wp-content/plugins/wdt-master-detail/class.masterdetail.wpdatacolumn.php and around line 51 you will find this

$formattedValue = "<form class="wdt_md_form" method="post" target="_blank" action="{$renderAction}"></form>

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

$formattedValue = "<form class="wdt_md_form" method="post" target="_self" action="{$renderAction}"></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}'>

and you have to replace with this

$formattedValue = "<form class='wdt_md_form' method='post' target='_self' action='{$renderAction}'>

That's for the button click.

For the row-click, in file /wp-content/plugins/wdt-master-detail/templates/md_modal.inc.php change line 52 just like you did the others, so instead of:

<form class="wdt_md_form" method="post" target="_blank" action="<?php echo $renderAction; ?>"></form>

Change it to this:

<form class="wdt_md_form" method="post" target="_self" action="<?php echo $renderAction; ?>"></form>

Let me know if that helps.

You're welcome, Jean!
