@ gjaya If you would to achieve something like this:
You can do the following:
<row>
<panel>
<input type="radio" token="sorttoken2" id="radio">
<label>Sort By:</label>
<choice value="button1">Button 1</choice>
<choice value="button2">Button 2</choice>
<choice value="button3">Button 3</choice>
<default>button1</default>
<initialValue>button1</initialValue>
</input>
<html>
<style>
#radio div[data-test="radio-list"]{
display: inline;
}
#radio div[data-test="option"]{
display: inline;
margin-top: 0px;
margin-right: 10px;
margin-bottom: 0px;
margin-left: 0px
}
#radio {
width:30%;
}
</style>
</html>
</panel>
</row>
Splunk dashboards are HTML, and you can have custom css in your application.css file for a Splunk app, so you can style any elements exactly how you like.
Care to elaborate..?
