Tags' groups allow you to collect a number of tags in one category; for example in “type of intervention” you can have the following tags: curative maintenance, preventive maintenance, improvement maintenance; or even classes of intervention: mechanical, electrical, boiler, etc.
To create a group of tags, simply click on the "Tags" menu. There, you can click on “group tags” and then on “create group”.
Then you just need:
to determine the name of the group of tags;
to select the different tags you want to add to this group;
to choose whether you wish that only one tag of the group can be selected during the creation of an equipment or task;
to specify whether you want the selection of a label to be obligatory or not when creating a task.
After that, all you have to do is to register the group of tags.
