How to stop Rshiny refresh data before I finish multiple input selection (before I hit enter)
I have 1 input in Rshiny that needs multiple inputs:
selectInput("selected_herd", "Select Herd", selected = herds_list[1], choices = herds_list, multiple = TRUE)
In the application, while I am adding multiple herds, the app refreshes the data before I hit enter. Is there anyway to stop this? and make the app refresh data only after I finish the input list and hit enter?
In the photo attached, you can see that I am about to start entering the list of herds, but the app already refreshes the data on an empty list and show errors.
What I want is the app to show result of the previous selection(photo 2) until I finish new selection and hit enter.
Anyone knows how to do this? Thank you very much!!!
Solution
So here is my solution:
In ui, I add an action buttion under the select herd box:
,actionButton("run_estimates", "Run Report",icon = icon('cogs'), class='btn-success fa-lg')
In server, I add 2 lines of codes at the beginning of my reactive function
input$run_estimates
ptpt <- isolate(input$selected_herd)
