self - supporting and
portable

adjustment

Explanation:

Straight ladders are designed to be moved (portable) but rely on leaning against a stable structure like a wall, so they cannot stand on their own (not self-supporting). Self-supporting ladders are a separate type like step ladders, and adjustable multi-section ladders are extension ladders, not all straight ladders.

Answer:

portable but not self-supporting
