Thank you Klas, but it isn't my question : I know what should be the link, but I can't manage to configure it in a field !
I have created a field type "Envoi" :
- type : "Button"
- task : "Save"
- Choice : "hide"
- Redirection : "None"
- Custom variables : "#my-tab"
but it doesn't work... When I click on the button, the form is well saved but the custom variable is not in the url.
Where else should I parameter it ?
