    "description": "The ComboBox control contains a drop-down list from which the user can select a single value. Its functionality is very similar to that of the SELECT form element in HTML. The ComboBox can be editable, in which case the user can type entries into the TextInput portion of the ComboBox that are not in the list.  <p>The ComboBox control has the following default sizing characteristics:</p> <table class=&quot;innertable&quot;> <tr> <th>Characteristic</th> <th>Description</th> </tr> <tr> <td>Default size</td> <td>Wide enough to accommodate the longest entry in the drop-down list in the display area of the main control, plus the drop-down button. When the drop-down list is not visible, the default height is based on the label text size.  <p>The default drop-down list height is five rows, or the number of entries in the drop-down list, whichever is smaller. The default height of each entry in the drop-down list is 22 pixels.</p></td> </tr> <tr> <td>Minimum size</td> <td>0 pixels.</td> </tr> <tr> <td>Maximum size</td> <td>5000 by 5000.</td> </tr> <tr> <td>dropdownWidth</td> <td>The width of the ComboBox control.</td> </tr> <tr> <td>rowCount</td> <td>5 rows.</td> </tr> </table>   <p>The <code>&lt;mx:ComboBox&gt;</code> tag inherits all the tag attributes of its superclass, and adds the following tag attributes:</p>  <pre>\\n &lt;mx:ComboBox\\n <b>Properties</b>\\n dataProvider=&quot;null&quot;\\n dropdownFactory=&quot;<i>ClassFactory that creates an mx.controls.List</i>&quot;\\n dropdownWidth=&quot;<i>100 or width of the longest text in the dataProvider</i>&quot;\\n itemRenderer=&quot;null&quot;\\n labelField=&quot;label&quot;\\n labelFunction=&quot;null&quot;\\n prompt=&quot;null&quot;\\n rowCount=&quot;5&quot;\\n selectedIndex=&quot;-1&quot;\\n selectedItem=&quot;null&quot;\\n \\n <b>Styles</b>\\n alternatingItemColors=&quot;undefined&quot;\\n arrowButtonWidth=&quot;22&quot;\\n borderColor=&quot;0xB7BABC&quot;\\n borderThickness=&quot;1&quot;\\n closeDuration=&quot;250&quot;\\n closeEasingFunction=&quot;undefined&quot;\\n color=&quot;0x0B333C&quot;\\n cornerRadius=&quot;0&quot;\\n disabledColor=&quot;0xAAB3B3&quot;\\n disabledIconColor=&quot;0x919999&quot;\\n dropdownBorderColor=&quot;undefined&quot;\\n dropdownStyleName=&quot;comboDropdown&quot;\\n fillAlphas=&quot;[0.6,0.4]&quot;\\n fillColors=&quot;[0xFFFFFF, 0xCCCCCC]&quot;\\n focusAlpha=&quot;0.4&quot;\\n focusRoundedCorners=&quot;tl tr bl br&quot;\\n fontAntiAliasType=&quot;advanced|normal&quot;\\n fontFamily=&quot;Verdana&quot;\\n fontGridFitType=&quot;pixel|none|subpixel&quot;\\n fontSharpness=&quot;0&quot;\\n fontSize=&quot;10&quot;\\n fontStyle=&quot;normal|italic&quot;\\n fontThickness=&quot;0&quot;\\n fontWeight=&quot;normal|bold&quot;\\n highlightAlphas=&quot;[0.3,0.0]&quot;\\n iconColor=&quot;0x111111&quot;\\n leading=&quot;0&quot;\\n openDuration=&quot;250&quot;\\n openEasingFunction=&quot;undefined&quot;\\n paddingTop=&quot;0&quot;\\n paddingBottom=&quot;0&quot;\\n paddingLeft=&quot;5&quot;\\n paddingRight=&quot;5&quot;\\n rollOverColor=&quot;<i>Depends on theme color&quot;</i>\\n selectionColor=&quot;<i>Depends on theme color&quot;</i>\\n selectionDuration=&quot;250&quot;\\n selectionEasingFunction=&quot;undefined&quot;\\n textAlign=&quot;left|center|right&quot;\\n textDecoration=&quot;none|underline&quot;\\n textIndent=&quot;0&quot;\\n textRollOverColor=&quot;0x2B333C&quot;\\n textSelectedColor=&quot;0x2B333C&quot;\\n \\n <b>Events</b>\\n change=&quot;<i>No default</i>&quot;\\n close=&quot;<i>No default</i>&quot;\\n dataChange=&quot;<i>No default</i>&quot;\\n enter=&quot;<i>No default</i>&quot;\\n itemRollOut=&quot;<i>No default</i>&quot;\\n itemRollOver=&quot;<i>No default</i>&quot;\\n open=&quot;<i>No default</i>&quot;\\n scroll=&quot;<i>No default</i>&quot;\\n /&gt;\\n </pre>",
