I have in a form 3 list lookups and besides I am using autocompleteplugin.js (http://words.usask.ca/sharepointsig/2013/10/25/replacing-a-drop-down-list-in-nintex-forms-with-an-autocompleting-textbox-using-jquery/). The problem is, that the loading time of the 3 list lookups is quite long. The form loads in 15-30 seconds.
I have tried to delay the loading of the list lookup by hidding them (Appearance -> Visible : no). This way the list lookups are not loading anymore on form load. What I could not achieve, is to change the visibility of these control, that the values load after the form is ready. I have tried with JavaScript, adding the visibility attribute and with CSS adding a class that has - visibility:visible !important;
None of the above affects the visibility of the control.
Does anybody succeeded to optimize performance by delaying the load of form controls?
