FLASH10: Indicating required form controls in Flash

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.


This technique relates to:

See User Agent Support Notes for FLASH10. Also see Flash Technology Notes.


The objective of this technique is to provide a clear indication that a specific form control in a Web application or form is required for successful data submission. The word "required" is added to the form control's accessible name, and a visual indicator is placed next to the label.


Example 1: Adding the word "required" to the control's accessible name

This example shows how to use the Accessibility panel to indicate a field as being 'required' to users:

  1. Visually, place asterisk character or some other indication adjacent to the form control's label.

  2. Use the Accessibility panel to combine the word "required" with the control's label in the "Name" field.

This approach is illustrated in the screenshot below:

Using the Accessibility panel to indicate a form control as being   required

This is demonstrated in the working example of Adding the word "required" to the control's accessible name. The source of Adding the word "required" to the control's accessible name is available.



For each required form control within a Flash movie, confirm that:

Expected Results

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
