Change Master / Detail Add Button on List Page

I found a bunch of articles that reference changing the “+” plus button on a list page, to a custom label like “Add Master Detail Record” etc.
I have a master table with multiple (3) details tables.
Everything is working, I just want to change the presentation a bit.

If I click on the master table, to display it in list form (i.e. registrationslist) I get the classic “+” super bold plus symbol button indicating “Master / Detail Add”. The button works fine, I just want to change it to an actual button with a label, that reads “Add Registration / Details”.

The articles I’m finding on this forum are great, but only if you’re not using multiple details tables. Since I’m using multiple details tables, the suggestions in this forum don’t work; they assume only one details table.

I have var_dump’d the registrationslist page to no avail; I have toyed with the (Table-Specific >> List Page >> Page_Render) as well as ‘Page_Load’ to no avail. Again, these tips seem specific to using only one details table.

If anyone has any more tips, I would be very grateful.

Thanks,

If you use multiple details tables, the “+” button is also for Master/Detail-Add with all the detail tables. If you want master with one detail only, you need to add your own button.

Thanks for your reply.
I want to keep the functionality of the button, it works just fine.
I just want to change its appearance.
Rather than appear as a “+” super bold plus sign, I want it labeled “Registration Details”.
This should be either client script or CSS or something.

Thanks again for any additional advice.
