Thymeleaf th:id Attribute: Dynamically Set HTML Element IDs

The "th:id" attribute in Thymeleaf is used to set the value of the "id" attribute of an HTML element. It is a Thymeleaf-specific attribute that allows you to dynamically set the id of an element based on the data in your model.\n\nFor example, if you have a model attribute called "user" with a property called "id", you can use the "th:id" attribute to set the id of an HTML element to the value of "user.id":\n\nhtml\n<div th:id=\"${user.id}\">...\</div>\n\n\nThis will dynamically set the id of the div element to the value of the "user.id" property in your model.
