[BUG] Dash documentation on Slider marks

Great software.

Describe your context On the Dash website there is an explanation of the Slider component https://dash.plot.ly/dash-core-components/slider Under the section “Marks and Steps” it says “[…] the slider will only be able to select values that have been predefined by the marks.” I’m on Chrome under Windows 10 but I doubt that’s relevant.

Describe the bug

When moving the slider you can select values not defined in marks. Additionally, you can’t select 7.65, a value defined in marks.

Expected behavior

I expected the slider to behave as described, i.e. limit the selectable values and have all defined values be available.

Thanks @grofte The issue is that step has a default of 1 (though this is never explicitly stated anywhere in our own docs - you have to go look at the component we wrapped, https://github.com/schrodinger/rc-slider to see that) and you have to explicitly say step=None to get the described behavior, which puts the text in contradiction with the example code.

Has anyone noticed (in the example above and in the docs) that the right-most mark (10 °F) wraps the characters after the space to a new line?

This is no bueno. One of those 80/20 Rule things that makes you pull your hair out when you’re burning the midnight oil to finish your project. Haven’t found a combination of style tricks or char code to work around it yet, either.

Otherwise, love the library & thx.
