Precision Mode
By default, the Rating precision is set to item.
To change the component precision, set its precision property to half. Setting the new value enables the user to select half value on the component icons.
Enabling First Item Half Selection
The min value is represented by the first rendered item. Because of this the component does not allow selecting the first half of the fist item since it's value is out of the defined min-max range.
The Rating does support first item half selection when the defined min-max range enables even number of possible selections.
For Example, the following configurations allows for a total of 5 possible values, which is an odd number of possible selection. This means that the Rating should disable half selection for one of the items.
<Rating
min={1}
max={3}
precision={"half"}
/>The possible values in the range of [1-3] are: 1, 1.5, 2, 2.5 and 3
If the application design requires us to enable first-item half-selection, it can be achieved by adding a sixth possible value for 0.5.
<Rating
min={0.5}
max={3}
precision={"half"}
/>Now, the possible values in the range of [0.5-3] are: 0.5, 1, 1.5, 2, 2.5 and 3
The Rating component will detect such use-cases when the precision is set to half and render the 0.5 value as the first-half of the first-item.
