I'm looking to have a dynamic input that can be either a Dynamic PickList OR A Dynamic Input such as text or DateTime.

$A.createComponent(String type, Object attributes, function callback)

I have been using the above to great effect with lightning input. However, when I try to do the same with lightning select, all of the guidance says that I can't have a dynamic amount of options as it seems each option has to be hardcoded like below!

    "lightning:select", [
            "aura:id": "input",
            "label": cmp.get("v.label"),
            "onchange": cmp.getReference("c.onChange")
            "option", {
                value: "Option 1",
                label: "Option 1"
            "option", {
                value: "Option 2",
                label: "Option 2"
    function(icmp, status, errorMessage) {
        if (status === "SUCCESS") {
            var body = cmp.get("v.body");
            cmp.set("v.body", body);
        } else if (status === "INCOMPLETE") {
            console.log("No response from server or client is offline.")
        } else if (status === "ERROR") {
            console.log("Error: " + errorMessage);

Now I know I can set the value/label of each dynamically, but I cannot seem to have a dynamic number of options matching the length of a list, for example.


from what I understood you want to bind options to variable, you can do this by using component.setReference. From what I remember it'll work like this icmp.setReference('v.options', cmp.getReference('v.myDynamicOptions'))

  • This will work for lightning select? Normally you have to do something like the below if setting static <lightning:select name="select1" label="How many tickets?" required="true"> <option value="">choose one...</option> <option value="1">one</option> <option value="2">two</option> <option value="3">three</option> </lightning:select> – KarlLivesey Mar 30 at 14:46
  • What format would myDynamicOptions need to be in? – KarlLivesey Mar 30 at 15:08
  • the same way you specified in your parameters array of {label, value} – ytiq Mar 30 at 18:05
  • ok. mb I forgot that you can't just use attribute for it. Then you need to create a custom component with options attribute which will create this child options for you in <aura:iteration> – ytiq Mar 30 at 18:08
  • I can't do that though as it could be a lightning:select or a lightning:input radiobutton so I cannot hard code it like that – KarlLivesey Apr 1 at 16:15
