Why does some Dashboard source code start with <dashboard> and others with <form>

[Gregski11]

hi I am fairly new to Splunk and inherited an environment and would like to know why some of our Dashboards source code starts with the <dashboard> tag where others don't have that tag and start with the <form> tag

furthermore if I add the <dashboard> tag above the <form> tag (of course terminate it at the end of the code as well with </dashboard>) I get the following Alerts / error:

This dashboard has no panels. Start editing to add panels.

If a dashboard has user inputs (radio button, time picker, etc.) then the <dashboard> element is replaced with <form>.  You can't specify both <dashboard> and <form>.

Be sure to use version="1.1" either way.

<form version="1.1">
...
</form>
