Hello Everyone
I’m currently working on customizing the Tiers module in Dolibarr, and I’d like to modify the form-filling mode in this module. More specifically, I’d like to adjust the way users interact with form fields, for example by changing field behavior, adding custom validation or modifying the layout.
The example below explains in more detail how I’d like to activate the fill-in mode.
I searched the files in the htdocs/custom directory but could only find one readme.md file. It seems that the module has no theme files or specific templates available for direct modification.
Could someone tell me where I can find the files needed to change the form fill mode? Also, any advice on best practices for making these changes would be greatly appreciated.
Thanks in advance for your help!
