Smart Input Placeholders
31
Overview
The Smart Input Placeholders plugin applies dynamic placeholders to Bubble input fields, offering two modes: Adaptive (shifts the text on focus) and Balloon (floats above like a label). This makes forms more readable, reduces errors, and increases completion rates.
Quick Setup
Input ID: specify the target input’s ID (e.g., email_input).
Style: choose Adaptive or Balloon.
Focus color: customize the placeholder color when the field is focused.
Compatible with Repeating Groups and Dynamic IDs.
Tip: Experiment with sizes and colors to create unique interactions. When to Use
Signup/login forms.
Checkout flows with multiple fields.
Mobile apps focused on readability.
Interfaces using dark mode or a minimalist layout.

Installation
In the Bubble editor, go to Plugins → Add plugins and install Nebula – Smart Input Placeholders.
Add the plugin element to the page containing the inputs.
How to Use
1) Input ID: set the target input’s ID (e.g., email_input).
2) Style: select Adaptive or Balloon.
3) Focus color: choose the placeholder color on focus (e.g., #9AA0FF).
4) RG/Dynamic: when using Repeating Groups, assign dynamic IDs for each cell.
Best Practices
Use unique IDs per field to avoid conflicts.
Test on desktop/mobile and in light/dark themes.
Avoid external CSS that repositions placeholders.
Troubleshooting
Effect not showing: verify the input ID and confirm the plugin element is on the same page.
Overlap in RGs: use dynamic IDs per cell.
Color not applying: review global styles/theme and any custom CSS.
