How can i make a textbox design like this?
Options:
- 
There is an extension for "beautifying" components: 
 [F/OS] 🛠️ ComponentUtil - Additional Tools For Visible Components (90+ blocks)
- 
You can draw graphics (inkscape, paint.net, drawplus etc) and use those for decoration (component background image, e.g. horizontal arrangement) 
- 
You can define your text boxes as tiny web pages, defined using HTML and CSS. 
Could you please show me some reference block?
You could try having a go yourself.....
It can be done using a couple of extensions:
@gordonlu310 's Beautify extension
and @VSATISH13 's OverlapView Extension
Here is an example using graphics - it won't tolerate phones that are of greatly different resolution to each other but you can tweak the sizes (%) in your Project to get a result like this:
Textbox_Decorated.aia (4.8 KB)

Thanks a lot..
How do I put the textbox into the image?
Try the example aia, you will see how it works
