How can I cancel the frame when drag the sentence

1. Quickly turn off the automatic border function
Method 1: through the options settings
Open Word → “File” → “Options”.
Select “Advanced” → Find “Cut, Copy and Paste” section
2. Uncheck the box:
“Show insertion options when dragging text”
“Show Paste Options button when pasting content”.
Click “OK” to save
3. Temporary solution
 Ignore borders when dragging:
Press ESC immediately after dragging text to cancel auto-formatting
or right-click dragging (instead of left-clicking) to avoid triggering the auto-border.
4. Disable auto-formatting completely (recommended)
Go to “File” → “Options” → “Proofreading”.
Click “Autocorrect Options”
In the “Apply formatting automatically when typing” tab:
Uncheck the “Borders” option
In the “Apply formatting automatically” tab:
Uncheck “Apply borders”.
5. Reset the default settings
 If the problem persists:
Close all Word documents
Press Win+R to enter:
winword /safe  
Test dragging text in safe mode
Restart Word normally
The problem is usually caused by Word's “Smart Paste” feature, so turn it off.
