Checking all children of a node should only check the root node

[williamboman]

Say you have made a selection like so;

Shouldn't All be the only item in the checked array in this scenario? Cause right now, every children will populate the checked array, and the root node will not be included. Or am I wrong here?

[jakezatecky]

There are a few ways to go about here:

1. Record leaf nodes in checked. Here, we only care about the leaf nodes. This is the current model.
2. Record upper-most nodes in checked. Here, we care about top-most checked nodes; the component needs to be intelligent enough to only record nodes that do not have a parent node checked. This is the model you are suggesting.
3. Record every checked node in checked. Here, we care about EVERY node selected, whether it is a parent, child, or leaf.

While the react-checkbox-tree component currently uses the first model, I do not see why we could not also support the other two models. Could be a component parameter.

[qodesmith]

Any progress on these models? I could use the 3rd one - "Record every checked node in checked".

[jakezatecky]

@qodesmith No progress has been made. Much of the component makes assumptions about check state based on child nodes. Nevertheless, of the additional models, the third one you are wanting is the easier one to implement.

A PR is welcome. Otherwise, I'll get to this when I can. I certainly agree that it would be useful to have implemented.

Hi, The component designed by you is very useful but
Even I Wanted 3d functionality:
checked array must contain all the checked nodes including parents.
Awaiting your response.

[VikramMaiya]

Hi,
Currently I am using "react-checkbox-tree": "^1.0.1"

I tried updating to your V1.1.0:
npm install react-checkbox-tree@1.1.0 --save

I got the following error:
No matching version found for react-checkbox-tree@1.1.0

[williamboman]

@VikramMaiya There are no 1.1.0 release yet.

[VikramMaiya]

Hi William,
checked array must contain all the checked nodes including parents.
Could you help me ?

[jakezatecky]

@VikramMaiya None of that is implemented yet. I only marked it for next release.

[VikramMaiya]

Hi jakezatecky,
Thanks for your quick response. How long will it take for the next release ?

[karan-chauhan]

Hi jakezatecky,
I also want all the checked nodes including parent, child. Can you please help me? And how long will it take for the next release..?

[karan-chauhan]

I solved some of my issue, but its not fully done. With this code, i can get the id of my parent, when i select all the values using parent. But if i deselect one of my child then it doesn't exclude the parent value from checked array. Here is the code that i changed:

key: 'toggleChecked',
        value: function toggleChecked(node, isChecked, noCascade) {
            var _this3 = this;

            if (node.children === null || noCascade) {
                // Set the check status of a leaf node or an uncoupled parent
                this.toggleNode('checked', node, isChecked);
            } else {
                //Change by karan
                this.toggleNode('checked', node, isChecked);

                // Percolate check status down to all children
                node.children.forEach(function (child) {
                    _this3.toggleChecked(child, isChecked);
                });
            }
        }

[nusudoers]

Any updates on the suggested models? I could really use the second option:
Record upper-most nodes in checked. Here, we care about top-most checked nodes; the component needs to be intelligent enough to only record nodes that do not have a parent node checked. This is the model you are suggesting.

[gazu36]

@jakezatecky Any updates on this? The third option is an incredible plus for me and would love that to be an "official" addition

[jakezatecky]

Model 3 is the one that can most easily be added. The second model would take more...thought. While some interest in Model 2 has been expressed, I can likely get a partial implementation with (Tesla) Model 3 in the next major release.

I have recently acquired some additional free time, so I think sometime before the end of this year is a good possibility. I am wrapping up some updates on one of my other libraries and then I will come back to this one.

[subhamayd2]

@jakezatecky Hi,
Thanks for the awesome component!! 😄
Although model 2 would be perfect, but is there at least any update regarding model 3?

[jakezatecky]

Model 3 has been fully implemented on the v1.6-dev branch. This can be activated by passing in checkModel="all" to the component. An alpha version of v1.6 has been published (1.6.0-alpha.0) should anyone wish to confirm the functionality or make use of it. A full feature release is planned for a later date.

It remains to be seen whether the second model will be included in the v1.6 release, as implementing its behavior is a bit awkward.

[joscmw95]

I just coded up a fork that does model 2 (if I understood it correctly).
Check it out, feel free to make it workable with the v1.6 release. Or ask me if any help is needed.

[bikashkomprise]

checkModel="all" does not work. I updated my package with src files from v1.6-dev

[worthlutz]

@jakezatecky I've done a little testing on v1.6.0-alpha.1 and checkmodel = all. It appears that only checkboxes which have the "black" check and not the "grey" check are listed in the checked array. Is this the intended result?

I am still thinking of the consequences of this. I suppose what matters is how the wrapping program uses the checked array. For me what usually matters is which node changed. This is usually the clicked checkbox or node and maybe all it's children depending on cascade status. If the parents and grandparents change, that is usually less or not important other than the visual changes in the tree.

I think I will put together some more test examples to expand my understanding of what is going on...

[jakezatecky]

@worthlutz, yes the partial nodes are intentionally not included in the checked array.

[jakezatecky]

@bikashkomprise can you post a live example showing your issue? I created a quick sandbox example that logs to the console all nodes when items are checked/unchecked:

[radufilipescu]

Hi, any updates on this cool new feature ? :D

[fuzunspm]

any news about this? I want to include not only checked leafs but their parent nodes in checked array

[ndaaktan]

checkModel="all" does works for v1.6

[AliBayatMokhtari]

checkModel="all" does works for v1.6

It does not select all the parents and only select the first parent if and only if all the children of a parent are selected.

[koi-annu]

How can I do this?

1. when one child selected then automatically include parent as checked result
2. add extra component input for example to each node

[Mitesh13499]

As asked by @worthlutz,
Would be very useful for me if we get all the grey (half checked) nodes as well when any child is selected in the sub tree.

[SaimMohanish]

Is there any update about half checked nodes

[Mitesh13499]

The only thing that helped me to get all the half checked nodes in onCheck was to override the code of the library as per my needs. all in the checkModel prop didn't help.
