Filter multiple items in a dropdown. [message #1001255]

I am working on filters in NatTable and I need a filter where I can select multiple items in a drop down to use in the filter.

Does anyone has an (example) implementation for that?

Hi,

well in fact this addresses two things:

1. Having a combo box in NatTable that supports multiple selection
2. A filter that can handle this

Currently NatTable doesn't support such a combo box. I worked on that a few months ago, but haven't got time to merge this into NatTable core yet. I will do this in the next few weeks.
After that we can have a look on how filters are able to react on that.

So I am only able to tell you that you have to wait some time to get that feature. At least this is what I can tell you.

Greez,
Dirk

Hi Dirk,

Thanks for your quick reply. That is correct.

Is it possible you post what you have till so far or maybe send me the code. Because I need to build such a thing at this moment.

Hi,

as I'm planning to adjust and commit it to the NatTable, I can send you what I have. Posting here would be too much, as I reimplemented the whole NatCombo and ComboBoxCellEditor. The main deal is to merge what currently exists with the one I implemented to have one control that can be configured for single/multi selection.

Where to send those files?

Hi,

with the major edit refactoring I committed a ComboBoxCellEditor that supports multi selection. Feel free to check if it is working for you. It should also cover the cases on rendering like you wrote me by email.

Is ComboBoxCellEditor that supports multi selection available in the latest snapshot build for 1.0.0? If so what control needs to be configured to toggle single/multi selection

Yes it is. Look at the ComboBoxCellEditor. There should be a constructor parameter for enabling multiselect. But I plan to push a change to that so it is not set by constructor but by setter instead soon.

The combobox with multiple selection works great.
Is it supported in the filter row? I'm trying to use it but it keeps filtering out all the rows.

Thanks,

Yes it is supported in the filter row. As stated in the New & Noteworthy page of 1.0.0, there is even a new filter row that works like Excel.

The reason why it might not work if you simply it to the filter row with further adjustments is that the logic is reverse to the usual filter row. On multiple selection you want to only SHOW the selected ones and FILTER all not selected, while with the usual filter row you FILTER everything that is not included.
