<div aura:id="lookup-div" class="slds-lookup" data-select="single" data-scope="single" data-typeahead="true">
        <!-- This is the Input form markup -->        
        <label class="uiLabel-left form-element__label uiLabel" for="lookup">{!v.label}</label>
        <div class="slds-form-element__control slds-input-has-icon slds-input-has-icon--right">
          <!--  <c:svg class="slds-input__icon" xlinkHref="/resource/SLDS104/assets/icons/utility-sprite/svg/symbols.svg#search" /> -->
            <lightning:icon iconName="utility:search"  size="x-small" variant="search" class="slds-input__icon"/>
            <!-- This markup is for when an item is currently selected -->
            <div aura:id="lookup-pill" class="slds-pill-container slds-hide">
                <span class="slds-pill slds-pill--bare">
                    <span class="slds-pill__label">
                     <!--   <c:svg class="{!'slds-icon ' + v.listIconClass + ' slds-icon-small'}" xlinkHref="{!v.listIconSVGPath}" />{!v.searchString} -->
                         <lightning:icon iconName="{!v.iconName}"  size="x-small" variant="process" class="{!v.listIconClass}"/>
                    </span>
                    <button class="slds-button slds-button--icon-bare" onclick="{!c.clear}">
                    <!--    <c:svg class="slds-button__icon" xlinkHref="/resource/SLDS104/assets/icons/utility-sprite/svg/symbols.svg#close" /> -->
                        <lightning:icon iconName="utility:close"  size="x-small" variant="close" class="slds-button__icon"/>
                        <span class="slds-assistive-text">Remove</span>
                    </button>
                </span>
            </div>
            <!-- This markup is for when searching for a string -->
            <ui:inputText aura:id="lookup" value="{!v.searchString}" class="slds-input" updateOn="keyup" keyup="{!c.search}" />
        </div>
