Sorting Combo Box Items on React

To sort a list of items in a combo box using React, we must create an array of strings which will be our list, and then we will map it out as an unordered list. Then we can also create the dropdown to select which type of sorting needs to be applied.

A Combobox is nothing but plain text input from the user that can provide a list of suggestions based on the input given by the user.

Types of Combobox in React,

• Simple combo box - that consists of an editable box with an attached list box containing a list of items.
• Dropdown list box - that consists of the static text box that represents the currently selected item by the user, and a list of items will show on the dropdown list.
• Dropdown combo box - it combines a dropdown list with an editable box. Thus we can either type an item's text or select an item from the dropdown list.

Here we are using a library called 'react-select' that allows us to select single or multiple values, search for available options asynchronously, and apply unique styles to a component in React. The sort() method in React allows us to sort the array elements in place and are returning the reference to the same array, currently sorted. In the sort() method, the default order of execution is ascending, built upon converting the elements into strings and then comparing their sequences of UTF-16 code unit values. There are two distinct types of sorting, one is the sort() method, and another one is sorted(). By comparing both, sorting is slightly faster than sorting and consumes around 24% less memory to store data. Sort is implemented only for lists, whereas sorted will accept any iterable. One of the most efficient ways to sort elements in a computer system is 'Quicksort'.

Here is an example of how you can sort Combobox items in React:

Fig : Preview of the output that you will get on running this code from your IDE.

Code

In this solution we're using React and React-select library.

Instructions

Follow the steps carefully to get the output easily.

1. Install the Node.js and React on your IDE(preferable Visual Studio Code).
2. Create React Application using npx create-react-app foldername.
3. cd foldername.
4. Open the folder in IDE.
5. Copy the code using "copy" button above and paste it in app.js file(remove the earlier code from app.js) and also refer demo given below for your reference.
6. Add export default statement at end of the code(like 'export default App;').
7. Open the terminal from IDE.
8. npm start to run the file.

You can also refer this url 'DEMO' for getting the above output.

I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.

I found this code snippet by searching for 'how to sort combo box items in react' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

1. The solution is created in Visual Studio Code 1.73.1.
2. The solution is tested on node v18.12.1 and npm v8.19.2.
3. React version-18.2.0.
4. React-select version-5.3.0.

Using this solution, we are able to implement sorting combo box items on react with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to implement sorting combo box items on react.
