Adding feedback vis shinyfeedback messes up the layout

[Martin-Jung]

shinyfeedback can be used to highlight mandatory and optional fields.
However the respective package to do so messes up the format of bs4Dash horribly.
Thus currently running on a backup solution.

This code for example does not work.

    shiny::observeEvent(input$studyname, {
      if(input$studyname=="") {
        shinyFeedback::showFeedback(
          "studyname",
          text = "This field is mandatory",
          color = "#d9534f",
          icon = shiny::icon("exclamation-sign", lib="glyphicon")
        )
      } else {
        shinyFeedback::hideFeedback("studyname")
      }
    })

Layout issues seem to popup only when condition is true during initialization.
Feedback now only added in response to added estimates for selected fields...
