Conditional Builder

Conditional builders let your UI change what it shows based on conditions. They achieve this by using keywords that specify the conditions and the corresponding UI elements to display. Here's a breakdown of the key aspects:

Keywords:

• Conditional Keywords: These are the core keywords that define the conditions for displaying specific UI content. The exact keywords and syntax will vary depending on the specific framework or templating language you're using. However, some common examples include:

  • if: Used to check a condition and display content if it's true.

  • else: Used to display alternative content if the if condition is false.

  • else if: Used to define additional conditions to check after an initial if condition fails.

• Variable Keywords: These keywords let you reference variables within your conditions. For example, you might use keywords like ${variableName} to access the value of a variable and incorporate it into your condition.

• Comparison Operators: These keywords represent operators used for comparing values and making decisions based on the outcome. Common examples include:

  • ==: Equal to

  • !=: Not equal to

  • <: Less than

  • >: Greater than

  • <=: Less than or equal to

  • >=: Greater than or equal to

Functionality:

• Conditional Logic: Conditional builders parse the specified keywords and interpret the provided conditions. If a condition evaluates to true, the corresponding UI element is included in the rendered output. Otherwise, it's skipped.

• Dynamic Content: This allows you to create flexible UI elements that adapt based on the data or state of your application. For example, you could display different messages or buttons depending on the user's login status or the availability of certain features.

• Improved Maintainability: By separating UI logic from presentation code, conditional builders can make your code more readable and maintainable. You can easily modify the conditions and displayed content without affecting the overall structure of your UI.

Examples (without specific syntax):

Imagine you have a variable isLoggedIn that indicates whether a user is logged in. You could use a conditional builder with an if keyword to display a login button if isLoggedIn is false and a welcome message if it's true.

Adding the Conditional Builder Widget

1. Add the Conditional Builder Widget

   • From the layout widget options, add the Conditional Builder widget to your interface.

2. Add Conditional Builder Items

   • Add Conditional Builder items to define the conditions. You can add as many conditional items as you need to handle different conditions.

3. Display Widgets Based on Conditions

   • For each condition, specify the widget to be displayed. For example:

     • On the success of condition 1, you can display a success text.

     • For other conditions, you can display appropriate widgets based on the outcome.

Benefits of Conditional Builder

• Personalized Experience: Show relevant content or functionalities based on user actions or app state. This creates a more tailored experience for each user.

• Streamlined Interface: Users only see what's important to them at the moment, avoiding unnecessary clutter and keeping them focused.

• Cleaner Code: By defining conditions within the Conditional Builder, you separate logic from the user interface. This leads to cleaner and more maintainable code.
