I am using react-dropdown-tree-select component for my project.
How can I change the order of the selected items?
The default selected item order is the same as the data list order, I want to change the order as the user choosing item order: every newly selected item will be appended to the selected list.
Thanks for your help!
In this case, you need to implement a middleware function inside onChange listener to rearrange the selected element and then update the state of data

I want to use DetailsList component https://developer.microsoft.com/en-us/fluentui#/controls/web/detailslist and select items. As I understand, the component doesn't provide us a prop to get selected items. I only see onActiveItemChanged prop which is only giving me single item but not all selected items.
I checked the question below, but it seems the answer doesn't work
Getting selected items in Fluent UI DetailsList
I wanted to create a state with an empty array and push or filter selected items into it, but there is also another problem. Scenario:
Click checkbox on header to select all items
If I click an item's checkbox, then it becomes unselected and other items still selected
If I click an item's any field instead of checkbox, then other items become unselected, and the one I clicked become selected.
Because of this reason -maybe I can also have other problem in the future-, I couldn't use state, as well.
I will be very glad if I can get current selected checkboxes on DetailsList component.
I found the answer.
import Selection from #fluentui/react
Add selection={selection} to DetailsList props
and then do this before returning the component:
const selection = new Selection({
onSelectionChanged: () => {
const selectedItems = selection.getSelection();
// Do something with the selected items'
console.log(selectedItems, "ewgergre");
},
});
I am new to VueJs , I am working on array of Elements, the requirement is by default we need to select the 3rd array position, Upon clicking Specific index to be selected.
For this i am using mandatory prop but by default it is selected to array position 1. i am using the toggle_exclusive class i can reach the o/p but after selecting Specific index complete row is selecting.
Please Help me to sort out this.
thanks.
What I'm trying to achieve here is to remove/disable the selected role after saving my selection. PLUS, if I press the X button at the panel below to remove my list of selections, I will be able to re-populate the list with the deleted roles recovered.
Screenshot of what I'm trying to achieve:
And at the moment, this is what I have:
controller js: http://pastebin.com/LDYrJQyf
html: http://pastebin.com/39G01ARm
Instead of using the $index. why not pass the id of selectedSkills given that it is an object and has a unique id. It would automatically update the table once you push it back.
I have 2 select option list, they are chained with this method : Chained Select List
I have added an input in order to filter all values in these 2 select with this method: Input Filter Select List
When a user type a word in the input, there are two case :
1/ If the user click on a word in the first list : it will show values possible in the second list
2/ If the user click on a word in the second list : it must show/highlight the 'parent' in the first list..
I don't know how to achieve the second case..
I'm open minded to every solution :)
Thanks,
since you have to do it using javascript..
There are two ways to do this
maintain an array of parents for the options available in the second list. get the values from array using arrday indexes of the select value in the list. use onChange() event on second list and populate the parent in the first list.
for second list, provide the option value to its parent.. i.e. when user selects an option in second list... as value it should return its parent... we will be able to populate the vallue in first list accordingly. please be aware that in this case it is overrding the actual values in second list.
Currently I have a very large of data model that is presented to the user with multiple options and events.
List item as checkboxes
Update the object's datetime when checked
Add checked item data to table array
Two options to deselect items: remove button on table or uncheck input
Post update to server when item is selected or deselected
I have been unable to create the correct knockoutjs script to make all events possible.
I definitely need help.
