根据选定的下拉列表值创建动态复选框 [英] Creating a dynamic check box based on selected dropdown list value

问题描述

我想基于下拉列表中的选定值文本创建一个动态复选框.

例如:下拉列表将具有:

(test1，test2，test3)，如果我是
选择Test2
它将创建一个名为test2的复选框，因此将动态创建该复选框.



此创建的复选框将具有一个并排的1个链接按钮，以及其他一些详细信息.并且在选定的下拉列表中将有5k条记录，因此仅需要的记录将创建一个复选框并提供进一步的功能

For example: The dropdownlist will have:

(test1, test2, test3) so if I am

this created check box will have side by 1 more linked button with few other details. and In the selected drop down list will more 5k records so whichever record wanted only will create a checkbox and go further functionalities
