Allow duplicate values in an input

[jbrooksuk]

Is it possible to have an input element which allows duplicate values? The reason is, I'm trying to build a form which allows people to enter ages of children, which can of course, be the same; twins, triplets etc.

Version 0.8 will allow this - if I understand your issue correctly - have a look at issue #76

[jbrooksuk]

Not quite.

Say I have an input element with the values 1-17. I need to be able to select any number in that range multiple times. So after I've finished picking my values, I could end up with 1, 1, 3, 5 as the output.

[jbrooksuk]

Any news on this?

[FoboCasteR]

Try last version.

[jbrooksuk]

@FoboCasteR am I needing to use any new settings? It's not working by default.

[FoboCasteR]

#76 - Here I used standalone version. Works fine with default settings.

[jbrooksuk]

No. This wasn't what I meant.

My problem doesn't involve optgroups. I just need to be able to select the same value more than once.

@jbrooksuk did you ever find a solution to this?

[jbrooksuk]

@ohaibbq, I'm afraid I never did.

i think this issue may need to have some modification to the selectize.js file

steps（with selectize v0.8.5）：

1：make the selected items can be duplicate when “create”
line:2494
CHANGE: addItem: function(value) {
TO: addItem: function(value, is_create) {

line:2502
CHANGE: if (self.items.indexOf(value) !== -1) {
TO: if (!(is_create && self.settings.enableCreateDuplicate) && self.items.indexOf(value) !== -1) {

note here i add a new option in settings named “enableCreateDuplicate” to switch this feature

2：sign as an user-create item in the createItem function
line:2625
CHANGE: self.addItem(value);
TO: self.addItem(value, true); // sign as an user-create item

3：add the new options where init selectize
$(select).selectize({enableCreateDuplicate: true});

now it should can accept duplicate values when create.
try it. ：）

EDITED (my bad coding the night huehue) so.

So, I got the same problem than @jbrooksuk and solved it.
You were right @airwin but this work only when you create an entry it's not perfect to work like I wanted (and I think like he wanted) and I didn't have what you are saying at the same line... :/ with the 0.8.5.

Just to be sure we are speaking about the same thing this code is to made possible to add the same searched value (so duplicated). I think some people here didn't understood @jbrooksuk request.
Little example, if you have [ "hello", "banana", "potatoes" ] as possible results, we wanted to be able to select 2 or 3 times hello, so our result could be [ "hello", "hello", "banana", "hello" ].

Hope is that you were looking for, I didn't wrote all of this for nothing xD

So code (I'll give my lines, but maybe it's different, don't care, just search the same thing).
We don't need the "is_create" bool because we want to allow duplicate entry on search and on create.

LINE 1686 in the addItem function scope replace the if(self.items.indexOf(value) !== -1) by
if ( !self.settings.enableDuplicate && self.items.indexOf(value) !== -1 )
This will allow to push a value that already exist ine your values

Now, after a long search inside the code (ok I just see it in the doc/usage, but looked before xD), there is an option to let the values already used.
set hideSelected: false when init your selectized item.

With this option and the new enableDuplicate, you will see them in the list, and will be able to add them again.

Done that's all.
I want to "stack" duplicatas in the same result by adding a xN prefix, I'll see how to do this ^^

Maybe pushing it in the next release ? It's not heavy and very usefull in my opinion.

[jbrooksuk]

@Inateno that's exactly what I want.

[airwin]

@Inateno nice solution~！

[xdbr]

Same use case here as @jbrooksuk ( @jbrooksuk: did you get the hacks outlined above to work for you?).

Judging by looking at the code as of 0.8.5 I can see changes that hint me towards there being an option inputMode: multi/single. However this is not mentioned in the documentation (usage.md).

Now I am confused whether this is already resolved and this issue to be closed as of 0.8.5 or not? How would I have to go about multiple values, as in @Inateno's example?

[airwin]

@xdbr there‘s not an official solution yet, u can use @Inateno 's code above.
