How to Conditionally Set Height in Ionic: A Step-by-Step Guide

If you are developing an application using the Ionic framework, you might encounter a situation where you want to adjust the height of a component based on user interactions, such as clicks. This feature can significantly enhance user experience by making your app feel more dynamic and responsive. In this guide, we will tackle the question of how to conditionally set height in Ionic, allowing components to expand or collapse based on user input.

Understanding the Problem

You've created a component in Ionic that displays various pieces of information in a structured format. However, you want users to have the option to expand or reduce the viewable area of this information, providing a cleaner interface that only shows essential data when needed. The goal is to adjust the height of your component based on whether it is expanded or collapsed, but you're not sure how to implement this functionality.

The Solution: Step-by-Step

Here’s how to implement a conditional height adjustment in your Ionic component:

Step 1: Remove Fixed Height

First, you need to remove the fixed height from the CSS class of your component. This will allow the height to be dynamic rather than static.
