Hi Giacomo,
to hide the Login form, you can use a Visibility Condition.
A Visibility Condition gives the possibility to hide or display an item in the grid depending to a certain condition. In your case, if the user is logged or not.
To create and use a Visibility Condition you follow the following steps:
- Create an Activation Expression that check if the user is logged. This expression returns a boolean value, true or false, depending on if the condition is fulfilled or not.
- Apply the Activation Expression to the Login form: select the form in the "Layout" View, move to the "Properties View" and open the "Condition" tab, then set the "Activation Expression" in the dropdown of the "Component Visibility Condition" property.
You can refer to the following article to learn more about the Visibility Condition http://www.webratio.com/learn/learningobject/getting-started-with-visibility-conditions-v-72.
Best regards.
