You can edit optional region settings after you’ve inserted the region in a template. For example, you can change whether the default setting for
the content is to be displayed or not, to link a parameter to an existing optional region, or to modify a template expression.

Create template parameters and define conditional statements (If...else statements) for template regions. You can use simple true/false operations,
or define more complex conditional statements and expressions.

In the Advanced tab you can link multiple optional regions to a named parameter. In the template-based document, both regions will show or hide
as a unit. For example, you can show a “closeout” image and sales price text area for a sale item.

You can also use the Advanced tab to write a template expression that evaluates a value for the optional region and shows it or hides it based on
the value.

1. In the Document window, do one of the following:

In Design view, click the template tab of the optional region you want to modify.

In Design view, place the insertion point in the template region; then in the tag selector at the bottom of the Document window, select the
template tag, .

In Code view, click the comment tag of the template region you want to modify.

2. In the Property inspector (Window > Properties), click Edit.

3. In the Basics tab, enter a name for the parameter in the Name box.

4. Select Show By Default to set the selected region to show in the document. Deselect it to set the default value to false.

Note: To set a different value for the parameter, in Code view locate the parameter in the section of the document and edit the value.

5. (Optional) Click the Advanced tab, then set the following options:

If you want to link optional region parameters, click the Advanced tab, select Use Parameter, then from the pop-up menu select the
existing parameter you want to link the selected content to.

If you want to write a template expression to control the display of an optional region, click the Advanced tab, select Enter Expression,
then enter the expression in the box.

Note: Dreamweaver inserts double-quotation marks around the text you enter.

6. Click OK.

When you use the Optional Region template object, Dreamweaver inserts template comments in the code. A template parameter is defined
in the head section, as in the following example:

At the location where the optional region is inserted, code similar to the code below appears:

You can access and edit template parameters in the template-based document.
