How to add simple label on dialog.xml in CQ5 AEM?

I have to design my CQ5 dialog as given in the following image. I have designed almost all the dialog but unable to add simple two labels side by side highlighted as red. Can someone please suggest how I can achieve it in dialog.xml ?

There is label xtype from CQ Widget API with style property which you can use as follows:

<label_1
    jcr:primaryType="cq:Widget"
    style="width: 50%;display: inline;margin-left: 100px;font-weight: 600;"
    text="Use as default filter"
    xtype="label"/>
<label_2
    jcr:primaryType="cq:Widget"
    style="width: 50%;display: inline;margin-left: 40px;font-weight: 600;"
    text="Show Advanced Options"
    xtype="label"/>

You can change style according to your need.
