Introduction

Lightning Web Components (LWC) have revolutionized the way we build custom user interfaces in Salesforce. However, one common issue that developers face is that LWC buttons are not visible in the Salesforce mobile app. This can be frustrating, especially when you've spent hours crafting a beautiful and functional UI. In this article, we'll delve into the reasons behind this issue and explore ways to make LWC actions visible in the mobile app.

Understanding the Issue

Before we dive into the solutions, it's essential to understand the root cause of the problem. LWC buttons are not visible in the Salesforce mobile app due to the way the mobile app renders components. The mobile app uses a different rendering engine than the desktop app, which can lead to inconsistencies in how components are displayed.

Why LWC Buttons Are Not Visible in Mobile App

There are several reasons why LWC buttons may not be visible in the Salesforce mobile app:

Rendering Engine: As mentioned earlier, the mobile app uses a different rendering engine than the desktop app. This can lead to inconsistencies in how components are displayed.
Component Size: LWC buttons may not be visible in the mobile app if they are too small or too large. The mobile app has a limited screen size, and components that are too small may not be visible.
Component Style: LWC buttons may not be visible in the mobile app if they are not styled correctly. The mobile app has a different style guide than the desktop app, and components that are not styled correctly may not be visible.

Solutions to Make LWC Actions Visible in Mobile App

Now that we've understood the reasons behind the issue, let's explore some solutions to make LWC actions visible in the mobile app:

1. Use the `mobile` attribute

You can use the mobile attribute to specify that a component should be visible in the mobile app. For example:

<template>
    <button mobile>Click me!</button>
</template>

2. Use the `mobile: true` property

You can use the mobile: true property to specify that a component should be visible in the mobile app. For example:

<template>
    <button mobile={true}>Click me!</button>
</template>

3. Use the `slds-mobile` class

You can use the slds-mobile class to specify that a component should be visible in the mobile app. For example:

<template>
    <button class="slds-mobile">Click me!</button>
</template>

4. Use the `slds-size` class

You can use the slds-size class to specify the size of a component in the mobile app. For example:

<template>
    <button class="slds-size--small">Click me!</button>
</template>

5. Use the `slds-style` class

You can use the slds-style class to specify the style of a component in the mobile app. For example:

<template>
    <button class="slds-style--primary">Click me!</button>
</template>
