User Interfaces for Extensions

Editable select lists

Extension UIs often contain pop-up lists that are defined using the 

select

 tag. In 

Dreamweaver, you can make pop-up lists in extensions editable by adding 

editable=

"true"

 

to the 

select 

tag. To set a default value, set the 

editText

 attribute and the value that you 

want the select list to display. 

The following example shows the settings for an editable select list: 

<select name="travelOptions" style="width:250px" editable="true" 

 editText="other  (please specify)">

<option value="plane">plane</option>
<option value="car">car</option>
<option value="bus">bus</option>
</select>

When you use select lists in your extensions, check for the presence and value of the editable 
attribute. If no value is present, the select list returns the default value of 

false

, which 

indicates that the select list is not editable.

As with standard, noneditable select lists, editable select lists have a 

selectedIndex

 property 

(see 

). This 

property returns -1 if the text box is selected.

To read the value of an active editable text box into an extension, read the value of the 

editText

 property. The 

editText

 property returns the string that the user entered into the 

editable text box, the value of the 

editText

 attribute, or an empty string if no text has been 

entered and no value has been specified for 

editText

. 

Dreamweaver adds the following custom attributes for the 

select

 tag to control editable 

pop-up lists:
