Hi @NicoDucou ,

It is added the backend adaptation and a simple frontend for testing the button actions. The frontend requires be adapted with the good components, validations. I let to @daniboygg for checking that part. This is my PR #4779

[NicoDucou]

Hi @christianbeeznest
Accepte el PR porque funciona bien y asi @daniboygg puede empezar lo de la interafaz.
Te dejo la tarea asignada al mismo tiempo que a Daniel porque hay un problema con lo links si se marca la casilla de poner el link en el homepage del curso, no se guarda la casilla y no aparece en link en el homepage como una herramienta del curso.
Te dejo revisar esto mientras Daniel avanza con la interfaz.

Hi @daniboygg
Ya esta listo para que puedas avanzar la interfaz.

I think there is missing information on the endpoint /api/links

The description of links and categories is missing. In chamilo 1.11 the description is shown to the user in the interface

@christianbeeznest @NicoDucou could you take a look?

[christianbeeznest]

Thank you @daniboygg , I will check. You can set a value harcoded in the vue code to avoid conflict with my next PR . when you finish the interface I can create a new branch with your changes. What do you think.

[daniboygg]

@christianbeeznest I've already created the pull request with the code in the frontend #4784, I skiped description for now.

Could you wait until the pull request is accepted? After that you can implemente the needed changes and I could take care of introduce the description in the UI. Is this ok for you?

I also added a placeholder button to switch to student's view because this feature was missing.

Is this feature only related to frontend, or does have some implication on the backend @christianbeeznest @NicoDucou ?
