I am developing a jQuery plugin for editable HTML tables. The table should allow inline editing, and certain columns (e.g., column 1 for “Position”) should render a dropdown for editing. However, instead of a dropdown, a textbox is being rendered.
What I Have Done:
I have implemented logic to check if a column is configured for a dropdown. If yes, it should render a element with predefined options.
If the column is not configured for a dropdown, it renders a textbox for editing.
I have also verified the column configuration and added console.log() statements to debug the issue.
Expected Behavior:
When I double-click a cell in column 1, I expect a dropdown with the following options to appear:
Developer
Designer
Manager
Analyst
Actual Behavior:

Debugging Output:
I added console.log() statements to check the column index and the dropdown configuration. Here is the output:ior (textbox) works fine.
Debugging Output:
I added console.log() statements to check the column index and the dropdown configuration. Here is the output:
Selected column index: 1
Dropdown columns value: undefined
This suggests that the plugin is not correctly detecting the dropdown configuration for column 1.
