Select within grouping variable #482

Closed rafiko1 closed 8 years ago

rafiko1 commented 8 years ago

Hi,

My data is alike the following format (hypothetically): I have a variable CustomerName (names ID of every customer), and every customer has a particular food that he likes saved under variable FoodName (can be for example pizza, spaghetti, tiramisu or whatever).

I ask my customer what are is most favorite food among those that he likes and that's what I want to select. For example Customer1: likes only pizza so I can select that because that's the only food he named. Customer2: likes spaghetti & tiramisu but his favorite is tiramisu so I want to select that.

And so on...

Is this kind of grouping possible to obtain with the angular-multi-select? I want to save both the CustomerName as the FoodName that I chose (Customer1 - pizza, Customer2 - tiramisu, etc.)

@rafiko1 ,

Disclaimer: I'm not sure I totally understand your situation..

However, since the grouping is basically a flat array, I can say that as long as you try to format your array like what the grouping feature needs, it should be possible.

In short; the input array for grouping is like..

[0]: GROUP ITEM 1: START [1]: ITEM 1.1 [2]: ITEM 1.2 [3]: ITEM 1.3 [4]: GROUP ITEM 1: END [5]: GROUP ITEM 2: START [6]: ITEM 2.1 [7]: ITEM 2.2

[X]: GROUP ITEM 2: END

I understand how the grouping works the way u described it. I'll probably have to do some formatting to my array.

My question is if it's possible: 1) To automatise this process of grouping when you always get different groups. One time it's GROUP ITEM 1, GROUP ITEM 2 - and another time it's GROUP ITEM 1, GROUP ITEM 2, GROUP ITEM 3. 2) To save the Group Item together with the chosen Item (now only Item is saved).

@rafiko1 ,

The directive is unable to do such automatic formatting. You are correct that, you need to format the array of object instead in your controller & pass it into the directive.

Saving is basically looping on the array of objects & manually detect the selected group items (or whichever item you need to save). Again, in your case, you most likely need to do a more specific saving function.
