I have custom object called 'Mall'. Once users have selected the Malls, there would be a button on the top right that says "Add to Account".
When the user clicks the button, it will ask them to select an account (they will be able to search accounts). Once they select an Account, there will be a button that says 'Add'. 
When they click add, the Malls that they selected on the list view would be added to the selected account they chose. 





How can I achieve this functionality in Lightening ?
