Need to implement Autocomplete on SharePoint Online list for

Just to reword my question - as per your current code you are using an input element to view suggestions when we start typing. However, my requirement is to get these suggestions in the existing SharePoint list column named Product Number (type of column: single line of text).   I have shared my column's code below. Where do you suggest I should add the ID(e.g. ID="tags") similar to your code (in the input element)?    

 

I just want to use the existing coloum to get the suggestions so that when I click on save button, my values do not disappear from the list item created. 

 

very simple modify your list view apply item ID decending order.always show newly added item first. 

Could you please tell me how can I store the selected value as a sharepoint list column value. I have a product profiles list which has a product number as a column with more than 5000 values.

 

My requirement is to view the product numbers in my another sharepoint list form as soon as I start typing the number. After the user saves the list item with the selected product number I should be able to view that selected item as a part of the new item created. 

 

In the code shared in the below link I could not find any option to store the value selected in my new form.

 

Can you please guide me.
