Quick Forms Application

To apply the Quick Forms feature to single-select dropdown controls, take the following steps:

• Drag a single-select dropdown control from the toolbox and drop it onto the design environment.
• Provide a caption for the control.
• To associate the control with an existing list in the database, specify the corresponding dropdown list in the Server ID field.
  • This can be done by entering a Server ID consisting of the name of the attribute followed by the name of the dropdown.
    • For example, “NameUser” would indicate that “Name” is the attribute and “User” is the reference to the list of users.
      

!If users prefer to create a custom list of static or dynamic items for the dropdown, they can skip this step and configure the control accordingly.

• Save the form and select Yes in response to the following prompt:
