How to use g:select within taglib in grails

Can anyone help me how to use the grails tags like g:select,g:label while creating a taglib functionality.

Following is my code.

I have create a taglib functionality 

 def dynamicAdvancedSearchTagLib={attrs, body ->
    String beanName = attrs.remove("beanName")
    def bean = request.getAttribute(beanName)
    out << createAdvancedSearchUI(bean)

}
def createAdvancedSearchUI(bean){
    StringBuilder sb = new StringBuilder();

    sb<<"""<fieldset class="search-advanced collapsed"style="border: 1px solid #CCC;padding:0px 21px 0px 21px;border-radius:8px 8px 8px 8px;min-height:24px;">
    <legend>
        <span id="advancedsearch"> <label for="advancedsearch">Advanced Search
        </label>
        </span>
    </legend>
    <g:form method="post">
    <div id="searchcontent">
        <div class="advanced-content-search">
            <label for="Criteria Name">Criteria Name <span
                class="required-indicator">*</span>
            </label>
            <select id="searchCriteria" name="searchCriteria" required="">
            *****<option value="0" selected="selected">Choose...</option>
            <option value="1">Something</option>
            <option value="2">Something else</option>
            <option value="3">Another choice</option>**
            </select>***
        </div>
        <div style="margin-left: 338px;">
            <label for="Enter Your Search Here"> Enter Your Search Here <span
                class="required-indicator">*</span>
            </label>
            <input type="text" name="advancedSearchText"
                value="" required="" />
        </div>

    </div>
    </g:form>
</fieldset>"""
}

Here my requirement instead of using the select html tag i need to use the g:select.

I have a static gsp page i have used g:select as 

    <g:select id="searchCriteria" name="searchCriteria"
                        from="${SearchCriteria?.values()}"  value="${searchInstance.searchCriteria}"
                        noSelection="${['':'---Select any One---']}" required="" />

The same functionality should has to be used while creating the taglib functionality..

If anyone knows how to use the grails tags while createing taglib, please help me.

You need to use something like this

def attrs=["id":"searchCriteria","name":"searchCriteria"]//fill other values
def formTagLib = grailsApplication.mainContext.getBean('org.codehaus.groovy.grails.plugins.web.taglib.FormTagLib')
formTagLib.select.call(attrs)

Here is a tutorial for the above that I found in Overwrite and reuse section

As an alternative you can also use

out << g.select(attrs)
