Does this specific 'step' feature exist? - possible feature request

[Shirin Heidari]

Can we do steps like: 0,100,200,1000,5000 (so the value would be changing and we would have markings on the slider, so in this case there would be 3 markings on the slider (100,200.1000).

If we can't do it right now, will it be possible to add this feature in the future please? Thank you

In Vue 3 you can do it by yourself using Teleport feature

As i see some demand on this feature i would like to share my solution to implement steps. Feel free to use it (just pass :discrete="true"):

<script setup lang="ts">
// this plugin has bugged typescript annotations. See https://github.com/vueform/slider/issues/71
// eslint-disable-next-line import/default
import Slider from '@vueform/slider'
import '@vueform/slider/themes/default.css'

interface Props {
  max?: number;
  min?: number;
  step?: number;
  discrete?: boolean;
  tooltips?: boolean;
  modelValue: number | number[];
}

const props = withDefaults(defineProps<Props>(), {
  min: 0,
  max: 100,
  step: 10,
  tooltips: true
})

const emit = defineEmits(['update:modelValue'])

const slider = ref(null)

const model = computed({
  get () {
    return props.modelValue
  },
  set (newValue) {
    emit('update:modelValue', newValue)
  }
})

const isArray = computed(() => Array.isArray(model.value) && model.value.length > 1)

const isDefault = (index: number) => {
  if (!isArray.value) {
    return (model.value as number) < index * props.step
  }
  const modelArray = model.value as number[]
  const first = modelArray[0]
  const last = modelArray[modelArray.length - 1]
  const value = (index + props.min / props.step) * props.step
  return last < value || first > value
}

const isActive = (index: number) => {
  if (!isArray.value) {
    return (model.value as number) >= index * props.step
  }
  const modelArray = model.value as number[]
  const first = modelArray[0]
  const last = modelArray[modelArray.length - 1]
  const value = (index + props.min / props.step) * props.step
  return last >= value && first <= value
}
