javascript - Devextreme load time -

i testing devextreme widgets , have designed login screen. have 2 dx-field that, know, loaded after javascript code executed. think produces ugly effect because rest of page loads before 2 inputs (maybe 1 second).

so, there way avoid problem , load inputs (and other widget) @ same time rest of web page?

edit: put scripts @ end of body tag , see if change head, such dx demos, works. in case, load scripts @ end

thank you.
