Oracle Apex - How to dynamically show/hide the '*' Required symbol on a textfield based on specific condition

In Oracle APEX, you can dynamically show or hide the '*' required symbol on a text field based on specific conditions using JavaScript and CSS.

Here's a step-by-step guide:

  1. Identify the Text Field: First, identify the text field item in your APEX page that you want to show/hide the required symbol for.

  2. Add a Dynamic Action: Create a dynamic action to trigger when the condition changes. The condition could be based on the value of another item, a page item, or any other criteria you choose.

  3. Action to Show/Hide Symbol: In the dynamic action, add JavaScript code to show or hide the required symbol based on the condition. You can use jQuery or standard JavaScript for this purpose.

  4. CSS Styling: Define CSS styles to hide or display the '' symbol. You can add a CSS class to the text field and define styles to show or hide the '' symbol using the :after pseudo-element.

Here's an example of how you can implement this:

Assuming you have a text field item with the ID P1_TEXT_FIELD and you want to show the '*' required symbol when another item with ID P1_CONDITION_ITEM is not null:

  1. Create a dynamic action:

    • Event: Change
    • Selection Type: Item(s)
    • Item(s): P1_CONDITION_ITEM

  2. Add True Action:

    • Action: Execute JavaScript Code

    • JavaScript Code:

      if ($v("P1_CONDITION_ITEM")) { $("#P1_TEXT_FIELD").addClass("required-symbol-visible"); } else { $("#P1_TEXT_FIELD").removeClass("required-symbol-visible"); }

  3. Define CSS styles:

    .required-symbol-visible::after { content: '*'; color: red; /* Customize the color as needed */ margin-left: 5px; /* Adjust spacing as needed */ }

This CSS will add a red '*' symbol after the text field when the required-symbol-visible class is applied.

By implementing these steps, you can dynamically show or hide the '*' required symbol on a text field based on specific conditions in Oracle APEX. Adjust the item IDs and conditions as per your requirements.
