How to add a new tab to a third party?

Hello,

I would like to add another tab to the third party to store some extra fields. I’ve looked through the wiki on the tabs system but cant seem to find the right descriptor file to add another tab. I am currently using 12.0.0 version of dolibarr. Thanks in advance!

Hi,

You need to developp your own module or use external modules like : https://www.dolistore.com/en/modules/354-CustomTabs--personalized-dynamic-tabs.html

I’ve created a new module and followed the steps in the following link. Even though I believe I followed the steps correctly, the new tab is still not visible. Is the wiki outdated or missing a step, or is the error in my code?
