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.

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.

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.
