AngularJS UI Select
This directive allows creating multiply drop-down lists with group related options. Value of selected options added to an array that available to AngularJS.
How does it work? Simple. Directive tells compiler to attached specific behaviour and create drop-down element from template.
To start, ensure all above dependencies are included as well as
ui-select.js directive and
Add HTML markup for select element first
ng-repeat="select in selectGroup">
Following attributes bind data with controller scope:
data="selectData" - drop-down data
single="selectedItem" - selected element by default
update="setSelected(select.box,item)" - specify selected element by given drop-down list
close="removeSelect(select.box) - remove given drop-down list
selectCrt.js initialising data for select element and setting selected item :
Three methods in controller respond to user behaviour:
- Add new drop-down list
- Get value of selected element
- Remove drop-down list
1) To add a new drop-down list
addSelect() method has to be triggered, in this example it's a button click. This method adds new item (select box) to an array. Having unique counter helps referring to a specific drop-down list when retrieving / updating values or removing drop-down list from array of elements.
2) Responding to select behaviour method
setSelected() obtains selected value from drop-down list. In this example default value is omitted. Single value per drop-down list will be stored in array of selected values, on changed event it's value will be updated accordingly. Lo-Dash library utilised to manage selected values in array.
3) To remove drop-down list method
removeSelect() respond to this action. Selected value from given drop-down list being removed from array of values first and then drop-down list being removed it's self.
