I have two dropdowns on dashboard but when I select dropdown values it gets automatically starts. I want to start dropdown values on button click. How to achieve this functionality.
I would store the dropdown values in context store and retrieve them when button press.
In example below i have added inject nodes to simulate button and dropdown selection, they can be removed.

i want pass trigger value and payload at same time....
please check my flow...
What trigger value are you talking about, you have not shown any values. Your question was how to send dropdown values. If you want more you will need to provide more info.
Sorry still do not understand your question.
Please create a simple small flow showing the issue and a description of what you are trying to do, then post here. copy and paste the flow json between backticks, as i do not download files from unknown persons.
i want to give payload value to rpi pwm pin with trigger time...
help with dropdown node
please reply to my query...

Corrected code formatting.
Please read the 'how to share code' link @E1cid kindly provided
[admin edit]
I did reply and you have not responded with the required info.
i asked for a simple small flow showing issue and a description of what you wish to do, I and others do not have time to work through a large flow, to work out where the issue is. So i ask once more for a small flow showing the issue you have and a description of what you want to do and what the input is and what outcome you wish. Until then i have no idea what you wish to do.
Please read
There has been a similar post a few weeks ago. This might help: Pull down menu to select delay? - #10 by fellinga
i have two dropdown nodes...
one for time selection and one for speed variation...
For speed variation and various trigger time i am using rpi pwm pin
i am sharing sample flow of my query

please kindly answer my question...
You posted a screenshot showing a NaN error from a node called HM, but there does not appear to be such a node in the flow you posted. The other error is from a debug node but you have not given that node a name so we don't know which one it is. Please give debug nodes names.
Please post just a small section of your flow that shows the problem. Not the whole flow with nodes that are not of interest.
i have two dropdown nodes...
one for time selection (PICK THE TIME) dropdown and one for speed variation(KM/HR) dropdown...
both dropdown values are given to raspberry pi pwm pin
For speed variation and various trigger time i am using raspberry pi pwm pin
