just like it's name, Repos can position element & pop element show with certain rule, use:
import Repos from './index.js';
$(input).on('focus',function(){
Repos({
ele: input,
pop: datepicker,
cnt: document.body,
offsetX: 0,
offsetY: 0,
alignX: 'inner-left',
alignY: 'bottom'
})
});
and now u will see a datepicker show when input focus, remember i just cal the position, not care show hide datepicker, just do simple thing.
by the way, it like https://github.com/HubSpot/tether, but i reference https://github.com/vadikom/poshytip for align rule
