Morphology
button + one's + lip
The verb 'button' (to fasten/close) applied to 'lip' evokes the image of fastening the mouth shut, so a learner who knows both words can plausibly infer 'keep silent'. This is a metaphorical but directly motivated extension rather than an arbitrary idiom, so it is predictable but not fully literal.
Etymology
The idiom button one's lip comes from the picture of closing your mouth like you button a coat: you press a button so the lip stays shut. That's why it means 'to keep silent' or 'not tell something'.
