If an attribute you want to set does not correspond to a property on the main tab of the element properties dialog box, you can set it on the Advanced tab.
The attributes you enter are not verified as valid. Make sure you check the HTML reference or the Language tab of the System Tree for valid attributes.
To add an attribute on the Advanced tab:
From Source view right-click the element's start tag or end tag and select Properties from the pop-up menu
or
In Page view select the viewable object, and right-click to access the Properties dialog box.
Double-click to type an appropriate value in the Attribute Name column and the Value column.
Do not include quotes when you specify the value.
If the value requires quotes (for example, if it includes spaces), they are inserted automatically.
To remove a setting:
Click anywhere on the line for the attribute you want to delete.
Press the Delete key or the Delete button.
