As soon as you mark a control required, the empty control displays a yellowish background gradient. Until users populate all required controls with valid data, they will not be able to submit the form because the Submit button will be disabled. 

You can change the color displayed by Required fields by modifying a Style and then applying it to your form/flow. If you prefer an asterisk to designate required fields, enable the Accessibility feature by checking the Accessible property on the form/flow Properties pane. This feature was built to allow visually impaired users to access forms. Enabling this property adds an asterisk (*) for all required fields. If users move ahead from that field without filling it, they will see the error, "You can't leave this empty <control name>".

...

This property determines whether the control is enabled or disabled when users first access your form. If unchecked, users may not enter a value in effectively making the control readonly.  Data cannot be entered until the control is enabled. (You can enable the control using a Rulerule.)

For example, say you are creating a wedding invitation form and want to know if the people completing your form are bringing a guest. Your form might include a text control for the guest’s name that becomes enabled only after users indicate (in another control) that they are in fact coming to the wedding.  

You are not permitted to disable grouping controls such as panels or repeats. However, there is an Enabled property for Sections, each of the columns in a Table and each tab in a Tab control. If "enabled" is set on Tab or Section, controls inside of these group controls would be enabled. Conversely, if the property is unchecked, controls inside of a section or tab would be disabled. This property will make it easier to write Business Rules. 

You can enable/disable the selection controls via rules thereby enabling/disabling all the selection control options. It is not possible to enable/disable individual options.

Disabled tabs are still selectable and disabled sections can still be expanded and collapsed. This is as designed. If you are trying to show/hide the contents of a tab/section, use the Visible property.

• Default - The background color for Default depends on the color scheme and is currently a grayish gradient in all color schemes. This is the message type for new controls
• None - has no border, decorator or color. Controls in migrated forms will have this type post migration
• Bordered - a border but no decorator or color.
•  Info Info - default decorator and blue background color.
• Success - default decorator and green background color.
• Warning - default decorator and yellow background color
• Error - default decorator and a red background color.

Another is the showhelp css class that is built into the Tight layout. For example, you can reduce white space even further with the Tight layout so that you have virtually no space between controls by selecting the hide label property on each control. This can be a way to implement a grid type layout as shown in this sample form below. 

When controls are this tight together there is no room to display the help icon for controls with help text. Notice that the first row of controls does displays the help icon. This is done by putting the string showhelp into the css class property for each control in the first row. This is a useful way to have help at the top of each column.

If you are using Live Forms in-house, Cascading Style Sheet code that was used in themes applied to forms/flows in previous Live Forms releases, can be added to a newly created style.css file in the frevvo.war file . The context parameter, frevvo.css.url, in the web.xml file must be changed to point to it

Custom groups with rules included when dropped back onto the same or another form, will contain a special "Prefix" property. The property will automatically be given a unique value if you drop the group onto the same form 2 or more times. This ensures that the group controls have unique element name. You can view the impact the prefix has on the element names by viewing the form's schema or the control's property panel. Using the prefix property, you can write a separate rule to manipulate the 2nd or greater instance of the custom control. Refer to this documentation for the details.
