In my article previously, I have discussed about how to create a widget to open the Many2many field in the new browser tab. Not a long ago I have created an improved and more complete version of that module.
In the previous version, not all Many2many fields with the many2many_tags widget could be opened in a new tab. We have to change the Many2many field with the many2many_tags widget to use the new widget, the many2many_tags_link widget manually. In this new version I change it so that all Many2many fields with the many2many_tags widget can be opened in a new browser tab automatically, without changing any code, just install the module. In addition, to open the data in a new tab you must right click the field then select Open Link in new tab, instead of left click on the field. Because I just realized that if we do a left click on the Many2many field with the many2many_tags widget on odoo 13, then we can change the color of the item.
I also add 2 other features, it is :
Open the Many2one field in a new browser tab.
And open the list view in a new browser tab.
I write this module for odoo 13, but after I tried it on odoo 14 it also work well. If you are interested for using or learning about this module please download it at my Github page. At the moment I have no plans to make a tutorial that discuss about the code or about the reasons why I write code like that, sorry 🙂
