# AutoComplete Control: Tagging Example with alwaysShowContainer

This AutoComplete interaction uses the `alwaysShowContainer` feature to allow users to find and select tags. Showing the set of previously used tags as a visual enhancement discourages unneccessary duplication of similar tags. As is common for tagging, comma- and semi-colon delimiters have also been enabled. Note that an initial query is needed on page load to get the container to display the first time with the full set of data. Since the container is meant to stay open, CSS is used to give it proper real estate on the page, including scrolling to show a potentially long list of tags.

View example in new window.

### Assign tags:

## Sample Code

Data:

YAHOO.example.Data.arrayStates = [ "Alabama", "Alaska", "Arizona", "Arkansas", "California", "Colorado", "Connecticut", "Delaware", "Florida", ... ];

CSS:

#myAutoComplete { width:20em; /* set width here or else widget will expand to fit its container */ padding-bottom:20em; /* allow enough real estate for the container */ } .yui-skin-sam .yui-ac-content { /* set scrolling */ max-height:18em;overflow:auto;overflow-x:hidden; /* set scrolling */ _height:18em; /* ie6 */ }

Markup:

<div id="myAutoComplete"> <input id="myInput" type="text"> <div id="myContainer"></div> </div>

JavaScript:

YAHOO.example.TagsAlwaysShow = function() { // Use a LocalDataSource var oDS = new YAHOO.util.LocalDataSource(YAHOO.example.Data.tags); // Optional to define fields for single-dimensional array oDS.responseSchema = {fields : ["tag"]}; // Instantiate the AutoComplete var oAC = new YAHOO.widget.AutoComplete("myInput", "myContainer", oDS); oAC.alwaysShowContainer = true; oAC.minQueryLength = 0; // Can be 0, which will return all results oAC.maxResultsDisplayed = 100; // Show more results, scrolling is enabled via CSS oAC.delimChar = [",",";"]; // Enable comma and semi-colon delimiters oAC.autoHighlight = false; // Auto-highlighting interferes with adding new tags oAC.sendQuery(""); // Populate list to start a new interaction oAC.itemSelectEvent.subscribe(function(sType, aArgs) { oAC.sendQuery(""); }); return { oDS: oDS, oAC: oAC }; }();
