I have a dynamic form depending on the value selected in a select menu which is the first form input.
The content of this first select menu is dynamic: it can contain zero, one or more values.
The select menu also has a placeholder to invite the user to choose a value.
My question is : if there is only one value in the select menu, could it be automatically selected and the form generated or is it better to have a common behavior to teach the user to select a value in the select menu and then fill the rest of the form ?
NB : users will use this form repeatedly, in most cases, the select menu will contain many values.
